No sound from rear speakers or subwoofer on the HW-Q90R
Currently, if you turn off a TV that has a HW-Q90R Soundbar connected to it, the soundbar will work when you turn the TV back on, but you may not get any sound from the wireless rear speakers or subwoofer. This can be fixed with a firmware update.
To perform a firmware update, you'll need to reconnect the speakers, update the soundbar and then update the subwoofer and rear speakers.
Please note: if you've already updated the speakers you will have to disconnect and reconnect the speakers before the update will apply
Reconnecting the speakers
If needed, you can follow the pairing instructions from the user manual
Updating the Soundbar
There are two ways to update your soundbar. You can either update via Wi-Fi or by downloading the update to a computer and transferring it to the soundbar with a USB stick.
If the firmware is any version lower than HW-Q90RWWB-1007.9 then tap on ‘Firmware Update’
Allow the unit to update before moving on to the next step
Please note: the SAT-HKA19WWC folder should not be placed within any other folder on the USB stick. The soundbar will not be able to read the files if they are within another folder on the USB drive
Updating the subwoofer & rear speakers
Once the soundbar has been updated you will need to update the firmware of the subwoofer and rear speakers.
Please note: if the soundbar has previously been updated at a different time, you will have to repeat the stage where you reconnected the speakers.
The soundbar will restart with the last known input displayed for around 20 seconds before it switches off
The update is now complete
